nice find. a lot of guys (racers) have started buying their vortice boots because of the replacement sole panel. some rearsets eat the soles up pretty quick. my old pair of vertebra's sole is still in great shape. i moved up to the ST air boots and wish I bought some perforated boots a long time ago.
Great find, Kevin. I figure I've got about a season's worth left on my Vertigo Corsa boots, as the Vortex rearsets that were on the GSX-R and the CRGs on the 848 are pretty aggressive on boots for grip.
